Missing Data Substitution

If you are compliant with Part 75, odds are that you have run into an issue with bad data that needed to be substituted.

Luckily, ProcessNow took care of the issue and filled in a value for the bad data. But how did ESC|StackVision know what value to substitute in?

Percent Monitor Availability

StackVision will use the PMA, or Percent Monitor Availability, to choose how data should be substituted. So the less you need to substitute data, the better your substituted values will be!

Also, the substitution routine will change depending on the kind of emission being substituted. The calculation can vary between using the average of the hour before the missing data and the hour after the missing data, or it can use a certain amount of the available data to substitute.
